Renal function, assessed by BUN and Scr, was worsened in folic acid versus vehicle mice, and improved only numerically after DMOG intervention (A). Ex vivo bioluminescence images. Quantitation of collagen I signal in folic acid+DMOG versus folic acid mice (B). In response to DMOG after folic acid injury, collagen I immunostaining in whole kidney cortex was decreased (C), the proportion of atubular glomeruli was reduced (D), and glomerular WT-1 density was not changed (E).
